General Description
A9508 is a high performance and low cost Sub1GHz ISM band system-on-chip (SoC) wireless transceiver. This device integrates high speed pipeline 8051 MCU, 16KBytes In-system programmable flash memory, 2KB SRAM, LCD driver, various powerful functions, and excellent performance of Sub1GHz GFSK/FSK transceiver. A9508 has various operating modes, making it highly suited for systems where ultra-low power consumption is required. A9508 has a high resolution 24bit ADC for temperature senor; a 8bit ADC for RSSI and 8 channels 12bit ADC for general purpose. Three kinds of serial communication port (SPI, I2C and UART) can interact with other device(s).

A9508 is one of AMICCOM sub1GHz family. It integrates AMICCOM sub1GHz transceiver well and offers a low cost solution with advanced radio features such as high output power amplifier and low noise receiver. Therefore, A9508 is very suitable for long LOS (line-of-sight) applications without the need to add an external LNA or PA.

The on-chip data rate divider supports programmable on-air data rates from 2K to 500Kbps to satisfy different system requirements. For a battery powered system, A9508 supports fast PLL settling time, Xtal settling time and on-chip Regulator settling time to reduce average power consumption.
